Hi everyone…
I have a problem with Katalon Studio. I can’t spy any object or start app. Katalon shows the following messages:
Record mobile: java.lang.NullPointerException
Spy: Failed to execute runnable (org.eclipse.core.runtime.AssertionFailedException: null argument:)

I have 1.8.1 version of Appium and my OS is: ubuntu 17.10
Please, could anybody tell me any solution? Thanks in advance.
